No, this is not supported yet by web js SDK. One workaround for you is to add these important logs as span events.

is there a way to add some context to a session so that we can query by session ?

&gt; any example for adding span events ?

Can you elaborate this?

for example i would like to query all the traces and spans for a specific userId

Yes, you can add custom attributes to these spans <https://opentelemetry.io/docs/instrumentation/js/instrumentation/#attributes>.

thanks will take a look at it :slightly_smiling_face:

Another question is was getting cors error in local and was able to add origins in docker file

but for k8's where do we add it ?

Yes, receiver config should be updated to allow origins.
